Catalytic Converter Laws

Rules for Replacing Converters
In 1986, the U.S. Environmental Protection Agency issued new
guidelines for the construction, efficiency and installation
of aftermarket catalytic converters. All CleanAir converters
listed in this catalog have been designed, tested and manufactured
to meet this policy.

In addition, CleanAir converter listed in this catalog is
appropriate for use under the current requirements of the California
Air Resources Board (C.A.R.B.).
E.P.A. guidelines state that replacement converters may be
installed only in the following situations:

1. The vehicle is missing a converter
2. A state or local inspection program has determined that
the existing converter needs replacement
3. Vehicles manufactured prior to 1996 must have more than
50,000 miles, and a legitimate need for replacement must be
established and documented
4. In cases of OBD Il-equipped vehicles (1996 and later), the
O.E. manufacturer's 8-year/80,000-mile warranty must have expired
and a legitimate need for replacement must be established and
documented.
Please note that Federal law prohibits removal or replacement
of a properly functioning O.E. converter.

When replacement of the converter is appropriate (as outlined
above), the E.P.A. further requires that:

1. It be installed in the same location as the original
2. It be the same type as the original (i.e., two-way, three-way,
three-way plus air/three-way plus oxidation)
3. It be the proper model for the vehicle application as determined
and specified by the manufacturer
4. It be properly connected to any existing air injection components
on the vehicle
5. It be installed with any other required converter for a
particular application
6. It be accompanied by a warranty information card to be completed
by the installer.
